Could be a bad ignition switch. Try starting it with a remote starter button kit. Turn the key to the run position and crank it with the remote starter button. If it runs then the ignition switch is most likely bad. Are you getting power to the ignition coil? HTH. -Jim

Yes I am getting power to the coil and I do not have a remoter start button...I get one spark upon turning it over...every time I turn the key on and try to start I get a single spark but no more until I turn it back off and try to start again

Try bypassing everything between the ignition switch and the solenoid and jump it for a second at that location. See if it wants to turn over from that spot. If not, it's not in the switch.

Do lights, radio, etc. work when the switch is off? Check for a corroded ground wire from the battery.

Check the ground wire from the throttle body to the firewall. If it gets real hot you could a loose connection at coil .
